It looks weird there are 2 bzImage images in $project/export/dist/boot if feature/initramfs-integrated or feature/initramfs-install used.

In theory, the single bzImage (meaning the bzImage without the bundled initramfs) should be not installed at all if creating the bundled image is enabled. And there is a new critical problem found:

Both RPMs will change the soft link bzImage to point to the real kernel image but the final result is determined by the installation order. If the end user intends to use the bundled image but the RPM containing the single kernel image is installed lastly, you can imagine what happens in next boot. All functions depending on initramfs will be not functional any more.

Steps to Reproduce

 Configure and build a standard wrl8 project with feature/initramfs-integrated or feature/initramfs-install
